3D VR Video Preview Object for Nausea Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality systems fail to address user discomfort and nausea caused by vestibular and visual mismatch, particularly when users enter or exit virtual reality videos, and struggle with incorrect initial location selection within 360° environments.
Innovation Solution
A method and system that generate three-dimensional virtual reality videos by stitching camera array frames, allowing users to select and move a virtual object, such as a sphere, to preview and enter desired locations within the video, with dynamic rendering based on user direction and resolution adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users enter and exit multiple virtual reality videos, then video selection flexibility is improved, but virtual-reality sickness is exacerbated due to overwhelming sensory input
Solution Approach 1:
The system provides a preview of the virtual reality video content before the user fully enters it. This preliminary action allows users to familiarize themselves with the environment and reduces the sensory shock of sudden transitions, thereby mitigating virtual-reality sickness while maintaining video selection flexibility
Solution Approach 2:
The preview functionality acts as an intermediary between video selection and full immersion. It provides a transitional state that buffers the sensory input, allowing users to adapt gradually rather than experiencing abrupt changes that cause discomfort
2Ease of operation
If users are placed at an incorrect location within a virtual reality video, then entry simplicity is improved, but user comfort deteriorates due to vestibular and visual mismatch
Solution Approach 1:
The system allows users to preview the virtual reality environment before entering, enabling them to identify and select appropriate entry locations in advance. This preliminary observation helps users choose locations that match their expected orientation, reducing vestibular and visual mismatch upon entry
Solution Approach 2:
The preview provides visual feedback about the virtual environment and entry points. Users can observe the spatial relationships and adjust their entry location selection based on what they see, ensuring better alignment between visual expectations and actual sensory input
3Manufacturing precision
If full resolution is rendered for the entire 360° virtual reality video, then visual quality is improved, but bandwidth requirements increase
Solution Approach 1:
The system renders the virtual reality video at full resolution only in the direction the user is looking, while other portions are rendered at lower resolution. This local quality approach maintains visual quality where needed while significantly reducing overall bandwidth requirements
Data Source
AI summary
A method includes generating a set of three-dimensional (3D) virtual reality videos by stitching together image frames of one or more environments captured by a camera array. The method further includes generating graphical data for displaying a virtual reality user interface that includes (1) selectable icons that correspond to the set of 3D virtual reality videos and (2) an object. The method further includes receiving, from a peripheral device, a selection of the object by a user of the peripheral device in the virtual reality user interface and an indication of a desire to move the object to be positioned in front of a first 3D virtual reality video from the set of virtual reality videos. The method further includes providing a first 3D preview of the first 3D virtual reality video within the object.
